Device for poisoning rodents



Feb. 5, 1935. J. A. BAILEY DEVICE FOR POISONING RODENTS Filed NOV. 28,1933 Patented Feb. 5, 1935 Q I JohnAmity Bailey, Willow's, cam. ,Apn'aetn November 2s, 933,seri lf v jvomias I 3 Claims.

This invention relates to a device for poisoning rodents.

An object of the invention is the construction of a simple and efficientdevice for quickly and easily placing poisoned grain in the holes orburrows of rodents.

Another object of the invention is the construction of a device which isprovided with a novel nozzle on its outer end, whereby when the deviceis thrust into a hole or burrow, and pressure placed upon the device, aquantity of poisoned grain will be quickly deposited'where the animalcan easily feed thereon.

A still further object of the inventionis the construction of a devicecomprising in combination a tube with a readily-detachable container atits outer end and at its inner end with a slidable spring-press nozzle.I

With the foregoing and other objects in View, my invention comprisescertain novel constructions, combinations and arrangements of parts aswill be hereinafter fully described, illustrated in the accompanyingdrawing, and more particularly pointed out in the appended claims.

In the drawing:

Fig. 1 is a perspective View of a device constructed in accordance withthe present invention, showing same in a discharging position.

Fig. 2 is an enlarged fragmentary vertical sectional view of thedischarge end of the device.

Fig. 3 is a sectional view taken on line 33, Fig. 2, looking in thedirection of the arrows.

Fig. 4 is a sectional view taken on line 44, Fig. 2, looking in thedirection of the arrows.

Referring to the drawing by numerals, 1 designates a detachablecontainer which is screwed into the threaded mouth 2 of the outer funnelportion 3 of the comparatively long pipe or tube 4. The container 1 isemployed for receiving the poisoned grain; it is usually filled beforebeing screwed into mouth 2.

The tube 4 is closed at its outer end 5 (Fig. 2). This tube is providedon its side with a discharge outlet 6. Within tube 4 is a closure disc 7contiguous to the outer end of outlet 6. End 5 and disc 7 produce acompartment 8 in tube 4. A

sliding sleeve-like nozzle 9 is on the outer end of tube 4. This nozzleis provided with a discharge outlet 10 which is adapted to register withoutlet 6 for permitting poisoned grain to be discharged from the device,as at 11, Fig. 1.

Normally the nozzle 9 is closed by reason of the following structure. Abolt 12 is placed in the end 5 with its head 13 incompartment 8. Aspiral spring 13 is around bolt 12 with its inner positing a suflicientamount of grain in the hole end pressing against end 5 and its outer endpressing against washer 14; washer 14 is mounted upon the outer threadedend of bolt 12. A nut 15 is on the outer threaded end ofbolt 12, againstI washer 14, within nozzle 9. A second nut 16 is 5 on bolt .12. Nut 15tightly engages the closed end 17 of nozzle 9, within said nozzle, andnut 16 tightly engages the outer face of end 17. The bolt 12 slides uponend 5 with its head 13 movable Within compartment 8. 7

After the container 1 has been loaded with the poisoned grain andscrewed into position as shown in Fig. l the operator is ready toproceed to place the grain.- in the holes, burrows, etc., of the. Irodents. He quickly thrusts the outer nozzled end 15 of the device intothe*hole,-pressing downwardly upon the same, which will cause a depositof poisoned grain, asillustrated 111mg. 1. I have found from extensiveuse that my device works efficiently and I that an operator can speedilydeposit poisoned grainin a great many holes in a short time.

Ihave'destroyed rcdents, by use of my device, in a relatively shorttime,over a great area of land.

By reason of the novel spring-press nozzle only grain is dischargedwhile the operator presses downwardly upon the device; a single jab ofthe-device is needed for quickly de- 30 or burrow for the animal oranimals residing therein.

Persons using my device never have to touch the poisoned grain, nor canpoison dust get into the eyes.

While I have described the preferred embodiment of my invention andillustrated the same in the accompanying drawing, certain minor changesor alterations may appear to one skilled in the art to which thisinvention relates during the extensive manufacture of the same, and I,therefore, reserve the right to make such changes or alterations asshall fairly fall within the scope of the appended'claims.

What I claim is:

1. In a device of the class described, the combination of a tube closedat its outer end, said tube provided in its side with an outlet, aclosure disc in said tube contiguous to the outer end of said outlet,said closed end. of the tube and said disc producing a compartment, asliding sleeve-like nozzle on the outer end of said tube, said nozzleprovided with an outlet adapted to register with the outlet of saidtube, a sliding bolt extending through the said closed 66 end of thetube with the bolt head in said compartment, said bolt extending at itsouter end through the outer end of said nozzle, a washer on said boltwithin said nozzle, a spiral spring in said nozzle around said bolt withits inner end pressing against the closed end of saidtube and its outerend pressing against said washer, a nut on said bolt between said washerand the outer end of said nozzle, and anut on said bolt against'theouterface of the outer end of said nozzle, substantially as, shown anddescribed.

2. In a device for poisoning rodents, the combination of a tube closedat its outer end and provided with a discharge outlet near said end, asliding sleeve-like nozzle entirely enclosing the outer end of saidtube, said nozzle provided with a discharge outlet being adapted toregister with said first-mentioned outlet, a bolt in said nozzle andfastened against movement upon the outer 1,990,262 end of said nozzle,said bolt extending into said tube, and a coil spring around said boltin-said nozzle and normally holding said nozzle in an extended position.

3. Ina device for poisoning rodents, the-com bination ofa tube closed atits outer end and provided with a discharge outlet near said end, asliding sleeve-like nozzle entirely closingthe outer end of said tube,said nozzle provided with a discharge outlet being adapted to registerwith said first-mentioned outlet, means for limiting outward slidingmovement of the nozzle fastened "fixedly against movement on the outerend of said nozzle and extending through the outer end of said tube, andmeans on said limiting means for normally "holding said nozzle in aclosed position and extended.
